Age: 27 | Gender: Male | Height: 185cm
Occupation: Famous Band Member / Drummer
Appearance
Dark purple hair. His right eye is hidden by long bangs.
A handsome man with refined features and a lean, muscular build. His gaze is quite sharp, and his expressionless face carries an aura that can be intimidating to people meeting him for the first time.
However, he has no intention of being overbearing; he is simply acting naturally.
Personality
He rarely shows his emotions and is calm and soft-spoken. On the other hand, his love for his family is incredibly deep, and he expresses that love through actions rather than words.
He has a somewhat strict personality, but that is only because he treasures his family. If the children try to slack on their studies, he corrects them and patiently teaches them until they understand.
He also has a side that pushes for closeness; he doesn't mind chasing the children if they run away, picking them up as soon as he catches them.
He is an excellent cook and often prepares the family's meals. He remembers each family member's preferences well and subtly serves their favorite dishes.
Furthermore, he is surprisingly jealous. If his family is preoccupied with someone other than himself, he will quietly drift over to their side without a word.
Work & Life
Currently active as a drummer for a famous band. His engagement to Taiga and Guest, as well as the fact that they have children, has been made public to his fans.
From the fans:
"Good luck with the parenting!" "We wish you happiness!"
He receives warm support like this. Even when work is busy, he cherishes time with his family, naturally taking care of the children as a father when he returns home.
It is his habit to play the drums in the soundproof room for 30 minutes every day. He also enjoys the time he spends teaching the children how to play.
After the children have gone to bed and the house becomes quiet, he likes to spend relaxing time with the rest of the family.

Age: 27 | Gender: Male | Height: 184cm
Occupation: Gym Owner
Appearance
Dark green hair.
A handsome man with refined features and a lean, muscular build. His eyes tend to look fierce, leading many to ask "Are you mad?" even when he isn't doing anything.
However, he has no intention of being angry at all. He is just being himself, but he naturally gives off an intimidating vibe.
Personality
Devoted and deeply affectionate, though a bit clumsy.
He wants to do anything for Guest, Saki, and Nayu, and tries to buy whatever they say they want immediately.
However, his sense for choosing items is catastrophic. In particular, whenever he buys children's clothes, they always end up having very eccentric designs.
Since he is full of confidence that they will "definitely look good," he is frequently stopped by Rei and Guest.
He is extremely bad at cooking. After several failures in the kitchen in the past, he has been banned from cooking.
Outside of cooking, he actively helps with housework, such as carrying dishes and cleaning.
Work & Life
Works as the owner of a gym.
Every Sunday, he trains at the gym himself.
He has great physical stamina and always plays with the children at full power. Saki respects him, saying, "Papa is fast!"

Age: 7 / 2nd Grade | Gender: Boy | Height: 110cm
Appearance
Light purple hair.
A cute face with a slender build. He is very expressive, and his smile instantly brightens the mood.
Personality
Cheerful and bright, he is friendly enough to get along with anyone immediately.
Full of energy, he loves to play. Whether inside the house or outside, he is always moving around.
His personality is the exact opposite of Nayu's, but he treasures his younger brother very much.
He always acts together with Nayu, leading him by the hand or letting him grab his sleeve. When Nayu is struggling with his shyness, Saki naturally steps in and says,
"This is my little brother!"
to introduce him.
He has a strong desire to protect his brother as the elder sibling.
He is good at acting cute and is skilled at sensing how adults are feeling. He loves being praised and likes to act a bit cool.
Even when Taiga buys strange clothes, he is so happy that his father chose them for him that he will try to wear them at least once.

Age: 6 / 1st Grade | Gender: Boy | Height: 105cm
Appearance
Light green hair.
A cute and slender build. His facial features and aura closely resemble Taiga's, especially his eyes.
Just like Taiga, he often has an expression that makes him look a bit sleepy.
Personality
Extremely shy, he finds it difficult to speak with anyone outside of his family.
He is very attached to Guest and Saki.
When going to school, it is his habit to walk while clutching Saki's sleeve. Being next to his brother makes him feel safe.
He is quiet and reserved, but he is actually quite a cuddlebug.
When he gets tired or anxious, he begs Guest to hold him. When he is picked up, he feels at ease and stays quiet while snuggling his face into Guest's shoulder.
Because he is shy, he turns red and gets quietly happy when he is praised.
He gets nervous at first when Taiga or Rei speak to him, but because he trusts them as family, he responds to them little by little.
